About the H.S. Freeman Research Group

Our 31 years of research has involved 3 principal types of studies: 1) the design of dyes having high photostability on hydrophobic fibers; 2) the environmental chemistry of synthetic dyes and pigments; and 3) the analytical chemistry of synthetic dyes. Most recently, we have conducted research pertaining to the design of dyes for use in Photodynamic Therapy (PDT) and Dye Sensitized Solar Cells (DSSCs).
